PROVIDING RELEVANT DIAGNOSTIC INFORMATION USING ONTOLOGY RULES

Embodiments of methods, systems, and storage medium associated with providing diagnostic information are disclosed herein. In one instance, the method may include applying a pattern to a log line included in a log file accessible by the computing device, to determine whether there is a match between the log line and the pattern. The pattern may be one of a plurality of patterns included in a collection of previously accumulated diagnostic information including one or more relationship descriptions between the pattern and other ones of the plurality of patterns. The method may further include generating and storing one or more additional relationship descriptions in response to determination of a match for the pattern. The additional relationship descriptions may indicate connections between the matched pattern and at least some other patterns included in the diagnostic information. Other embodiments may be described and/or claimed.
